System and method for monitoring human interaction

ABSTRACT

A method &amp; system for human interactive proof (HIP) is provided. A user is provided to respond a query linked to a logical captcha object or an analytical captcha object. Upon receiving inputs from the user, the correct information of the said captcha &amp; the user&#39;s input is compared. If the user&#39;s input and the correct information of the captcha object matches then the user is authenticated as human, else the user is authenticated as not a human.

TECHNICAL FIELD

The present technique relates to authenticate human interactive proof (HIP) using a query based logical captcha object or analytical captcha object provided with interface. The captcha is displayed at user's interface at his system. The user is requested to respond the query. For correct response, the user is authenticated as human else the user is not authenticated as human.

BACKGROUND OF THE INVENTION

Various reports are indicating enhancing dependency on WWW (word wide web) as predominant medium for communication. Indeed, internet has emerged as the most essential & cost effective medium for communication & interaction for the corporations or the institutions or the individuals. Thereof, a lot of security concerns have also been arisen while exercising any internet based transactions. Additionally, under many circumstance, the service provider or a user essentially expects a responder should be a human where is human is providing response using a user machine i.e., the response is not a machine generated (for e.g., a bots or softwares). Therefore, a desire of human interactive proof has evolved. For example, in an internet based voting by a service provider, for example whether brand “A” is better or brand “B”, the service provide essentially expects a human as responder. However, various software programs have been developed which are enabled to provide favorable response. Those softwares are programmed to provide a favorable response, therefore the voting result is fabricated and final result is not a true result. To affirm a human response & evade the software program or bots to provide any response, many techniques have been developed. One of very famously and extensively used technique in ensuring human interactive proof is providing a CAPTCHA object to the user machine. Conventionally, the CAPTCHA objects are some images or pictures or alphanumeric texts or combinations, which are intended to display at user's interface. Conventionally, a query like “what is the image” or “write the name of the object displayed” or “enter the displayed text” or other similar questions is also asked. On spotting the CAPTCHA object, the user is requested to provide a suitable response for the CAPTCHA in an input box. Any normal human user is able to recognize or read the challenge provided in the CAPTCHA, and he is able to provide the appropriate response thereof. This process establishes whether the interactive user is a “human” or a not a human i.e., “machine” or bots or softwares etc.

Since, these images or the alphanumeric texts based CAPTCHAs displayed at user's interface are static and therefore it suffers other grave setbacks as well. The techniques like optical character reorganization (OCR) have been managed to break the CAPTCHAs mentioned above. The OCR system comprehends the image or the text presented at system's interface and feeds the response as human thereof. Similarly, other software programs may also be devised which contains a list of plausible images and dictionary connotation of the images. The software fetches the image displayed at client system interface and compares it with the images contained in the listing. If the image is matching, the software is enabled to select the dictionary connotation of the images and provide it as a response at input box. For example, if a lion is displayed at the interface of system, the software program fetches the image and compared with the list of stored images. On matching with image of lion, the dictionary connotation i.e., lion is fed as user's input. So softwares or machines are able to provide the response and defeats the object of human interactive proof.

As a result, an improved captcha is desired to establish human interactive proof where the captcha should be designed in such a way that it is neither easy for a software program to solve and nor too hard to infer by a human & providing the response for the captcha thereof.

BRIEF SUMMARY OF THE INVENTION

The summary is provided to introduce a selection of concepts in a simplified form that are further described below in the detailed description. This summary is not intended to identify key features or essential features of the claimed subject matter, nor is it intended to be used as an aid in determining the scope of the claimed subject matter.

In one embodiment of the technique, a method for authenticating a human interactive proof (HIP) is described. In one embodiment of the technique, a method to authenticate a human interactive proof is described. The method involves providing an interface embedded with a logical captcha object or an analytical captcha object to a user. A query associated with the captcha is also provided and displayed at user machine interface. The captcha object creation & the associated query creation is a dynamic process. The captcha, the associated query and the expected response for the query are stored on machine readable medium. The user is enabled to provide response for the query associated with the logical or the analytical captcha object. On receiving the response, the user's response is compared and validated with information stored for the captcha on machine readable medium. If the user's input is correct, the user is authenticated as a human; if the user's input is incorrect, the user is authenticated as not a human. In one example, a captcha object comprises “6 squares” and the associated query to the captcha object is “type the numbers of squares” or “provide image type and numbers of the images”. The captcha object & the associated query are displayed at user machine interface. A normal human is adequately competent to recognize the “the numbers of squares” or able to recognize “image type and number of images” as requested in the query. The user's response & the information stored on computer readable medium are compared. On matching the response, the user is authenticated as human otherwise the user is determined as not a human.

In yet another embodiment of the present technique, a system for HIP is disclosed. The system includes a generating module to generate a logical captcha object or an analytical captcha object and a generating module to generate a query linked with query; a communicating module, for example internet, to communicate the generated captcha & the linked query at the user's interface and to receive response from the user thereof; and a authenticating module to compare the response of user with the forwarded motion random HIP.

As such, the present description should be considered as merely illustrative of the principles of the present technique and not in limitation thereof, since the present technique is defined solely by the claims.

As will be appreciated by people skilled in the art, to best understand the present invention it is important to be familiar with the definition in which it is used:

“User” or “client” in the present technique represents to any person or entity desiring to use or access to some-kind of protected service or application (e.g., opening of web-based new account, access to available web-based account, online transaction etc.)

“Client machine” or “client's computer system” or “user's machine” or “user's computer system” or “client system” or “User system” in the present technique includes personal computers, desktop, server computers, hand-held device or laptop devices, multiprocessor systems, microprocessor-based systems, network PCs, mobile devices, personal digital assistants, smart phones, digital cameras, kiosks, ATM and the like.

“Interface” or “User interface” in the present technique represents interface of “client machine” or “client's computer system” or “user's machine” or “user's computer system” or “client system” or “User system”.

“Server computing system” or “Server computing machine” represents a server machine or server system or server application or combinations thereof and other necessary hardware or software components, to facilitate secure access to the server.

“Generating module” in the present technique represents a stand alone unit or an integrated unit of server computing system.

“Communicating module” in the present technique represents a stand alone unit or as a part of server or combinations of both that is provided to connect user's client machine with server computing system through a network.

“Online Network” or “online” or “network” in the present technique represents internet, or a local area network, or a wireless network, or a wide area network, a point-to-point dial-up connection, and the like.

“Online services” or “internet based services” includes opening one or more new online accessible accounts (i.e., email account, online bank account), accessing existing online account, validating an input during an online poll, exercising online transaction, accessing online data access, responding to an online service, online response validation and the like. The online service is maintained at service provider end.

“Authenticating module” in the present technique represents a stand alone unit or a part of server computing system.

“Unit” or “module” represents a stand alone unit or combination of units enabled to execute desired actions.

Referring to the figures, FIG. 1 is a flowchart illustrating a method of providing a captcha to a client and receiving the input from the client according to one embodiment of the technique. The method starts with step 101, a client desiring to utilize an online service (e.g., opening a new online email account) using a client machine (e.g., a desktop) sends a request to a server computing machine of a service provider. The server computing machine and the client's machine are linked though a network system e.g., internet. A webpage is transmitted at client machine's interface using a network, as represented in step 103. The webpage is embedded with a logical captcha object or an analytical captcha object and a query linked to the embedded captcha object. The captcha object includes an image or group of images or numeric values or alphanumeric texts. As apparent to those skilled in the art, distortion of the captcha contents i.e., images or the numeric values or the alphanumeric text is not out of the scope of the present technique.

Further, color of contents of the captcha object may be diverse e.g., in a numeric values based captcha object, one or more selected numerals may be presented in red color while other colors recognizable a human. For example, for a numeric captcha object “89763”, the numerals “8”, “9”, “7” “6”, and “3” are displayed in red color, blue color, green color, pink color, and brown color respectively. The associated query for the captcha object may be “what is product for numerals in red color and pink color” or “type the sum of numerals shown in blue color, green color, and red color” and so on. The information about the captcha and the linked query and the projected response is stored at server computing machine end. Therefore, only a human intelligence can decipher the captcha object.

According to one another embodiment, the query linked to the captcha may be forwarded separately in another dialogue box along with webpage embedded with the captcha object. The captcha object & the dialog box with a linked query are presented at client's machine.

The client is requested to solve the query and submit his response through an input receiving box displayed at webpage. The response from the client's machine is received as represented in step 105, and saved for validation. In next step 107, the client response for the captcha is compared with stored information of the captcha. If the response received from client's machine matches with information stored of the said captcha object, the client using the client machine is authenticated as a human, else the client is not a human i.e., some software program or bots.

FIG. 2 is a depicting an exemplary example of a logical captcha object or an analytical captcha object according to one embodiment of the technique. The captcha objects are termed as logical captcha object or an analytical captcha object since a human with a normal intelligence can only solve present challenge displayed in captcha. For example in FIG. 2 a, some numeric integers are displayed in a matrix. The matrix contains a few columns and a few rows. Each cell of the matrix may or may not contain any numeric integers. Also, all cells of matrix may have similar background color or may have varied different colors. Also, the numeric integers of cells may be presented in same color or in different colors.

As mentioned in any of earlier section, the associated query is presented at user machine interface. The associated query, for example for FIG. 2 a, is based on simple mathematical logics or analytical studies which is simple for any human with normal intelligence. For example, the mathematical logic is a query on summing the numeric integers or multiplying of numeric integers or subtraction of numeric integers or dividing of numeric integers or combinations. Therefore, the query for the CAPTCHA object can be “provide the sum of the numeric integers presented in first row” or “provide the sum of the numeric integers presented in first column” or “provide the sum of the numeric integers presented in red color (or any other color presented in the captcha object)” or “provide the product of numeric integers of presented in red color & green color” or the like. For example if the captcha object FIG. 2 a is presented to the client machine and the associated query presented is “provide the summation of the numeric integers presented in first row”, the expected input from user's machine will be “13”. It is well apparent to the people those skilled in the art that other mathematical logic based queries can also be generated and those queries are also within the scope of present technique. It is also well apparent to the people those skilled in the art that change in background color of the cells or the method or representing of numeric integers may vary and within the scope of the present technique.

An instruction for providing the input for the said captcha and submitting the response is presented. On receiving the inputs from the client's machine, it is compared with stored information of the said captcha. If the response received from the client's machine and the stored information associated to the captcha matches, the client machine user is authenticated as human otherwise the client machine user is authenticated as not a human i.e., bots or softwares or machines.

A few more examples of captcha object such as FIG. 2 b or FIG. 2 c or FIG. 2 d are displayed wherein solving of these captcha objects involve human intelligence. In FIG. 2 b, for example, six embedded squares are displayed. As apparent to the people those skilled in the art, various modifications are possible for example diverse size of squares (some square are smaller and few others are larger, apparent enough to distinguish among them) or different or same colors of the squares or different or same background colors of the squares etc. A user can be requested to “provide number of squares displayed in the captcha object” or “provide total number of squares in red colors (if one or more squares are displayed in red color)” or “provide total number of squares in having red background colors (if background color of one or more squares are displayed in red color)”. Also, as apparent to people those skilled in the art, there can be one or more circles or one or more triangles or any other one or more images or combinations wherein these images be easily recognized by human intelligence. Various other modifications such as one or more circles or one or more triangles or any other one or more images or combinations, and/or diverse or similar colors of images and/or diverse or similar background colors of images are possible and within the scope of the present technique. With every instance, a new captcha is generated and presented to the client machine. A query linked with the captcha object is also generated and presented to the client machine.

Similarly, in FIG. 2 c, territory maps of few select countries and the national flags of those countries are displayed. A human with normal intelligence can recognize the countries and the national flag of the countries. The client is provided a request to match the national flag and the country it is associated with. For FIG. 2 c, the correct result is “1C2B3A”. If the response received from the user matches with the correct result, the user is authenticated as human, else the user is not a human i.e., bots or software program or machine program. In FIG. 2 d, various types of shapes & number of shapes are displayed. A user is requested to match the type of shape with the number of shape. For FIG. 2 d, the correct result is “1C2A3B”. If the response received from the user matches with the correct result, the user is authenticated as human, else the user is not a human i.e., bots or software program or machine program. As apparent to people those skilled in the art, various modifications such as diverse colors of shape, background color, insertion of different number of shapes are possible and within scope of the present technique.

Moving to next diagram, FIG. 3 is representing a flow diagram illustrating a method of generating a logical captcha object or analytical captcha object according to one embodiment of the technique. At many instances, for example in online voting or in creating new online account or during online transactions or during responding to emails or at many other similar instances, a proof of human interactive proof (HIP) is essentially required. The present technique provides a method of HIP using a logical captcha object or analytical captcha (samples of captcha shown in FIG. 2). The captcha object presented to the client is a part of web-page, however, the captcha object can also be provide in separate dialogue box.

To solve the knowledge based & mathematical skill captcha object, for example as shown in FIG. 2, a user has to recognize the item displayed and thereafter he has to use his intelligence to solve the query associated with the captcha object. In step 301, he captcha object is generated using a captcha object generation module. The captcha object is generated dynamically, more preferably on fly according to one embodiment of the present technique. As represented in step303, a query related to the said generated captcha object is created using a query generating module. For example if FIG. 2 a is generated as a logical captcha object or analytical captcha object, then an associated query presented to the user is to “provide the sum of the numeric integers shown in first row”.

As shown in step 305, the captcha object and the associated query are provided to the client machine through a network. On receiving the captcha and the associated query, a user is requested to provide his response (block 307) in an input box presented along with web-page. On submitting the response for the query, the response is received & captured as depicted in step 309. Subsequently, the response is validated by matching with correct result of the said captcha as represented in step 311. If the response received from the user machine matches with the stored correct result for the said captcha object, the user is authenticated as human, else the user is authenticated as not a human.

Referring to FIG. 4 is a flow diagram representing a method of human interactive proof according to one embodiment of the present technique. As an example of human interactive proof, the method starts with a user request to exploit an online service as represented in step 401. A user desiring to exercise an online service drives a request to the server using a client machine. The client machine and the server are interacting using a network. The server can coupled with other processing modules and databases. On receiving a request for an online service to a server, a client machine is provided a web-page along with a logical captcha object or an analytical captcha object and a linked query (block 403) wherein the logical captcha object or the analytical captcha object and the associated query type is described in any of the earlier sections.

Subsequently, a web-page along with a captcha image and a linked query is displayed at client machine interface. The web-page also contains space (i.e., input box) to provide input by the user. On submitting the response by a user using client machine, the input is captured at server as represented in step 405. The user response for the captcha object is compared with stored information for the said captcha object as a process of validating the user's response as indicated in step 407. If the user response is correct (block 409), the user is authenticated as human (block 411) and the human interactive proof authentication process is completed (block 415). If the user response is not correct (block 413), the user is authenticated as not a human (block 413) and the human interactive proof authentication process is completed (block 415).

Moving to next diagram, FIG. 5 is a schematic diagram of a system illustrating human interactive proof according to one embodiment of the present technique. As shown in the FIG. 5, section 519 indicates user's interaction parts and section 521 represents authentication processing parts of the system 500. The system includes a client machine 503 (e.g., a general purpose computer machine) meant to used by a user, a network 505 for example internet meant to interact client machine and various other units with server system 507, and various other processing modules such as unit 509 or unit 511 or unit 513 or unit 515 or unit 517 or other additional requisite units wherein these exemplary units may be enabled to process as authenticating module or captcha generating module or query generating module or storing module or validating module or; also these unit may be a integral part of the server system or can be separate & stand alone units. Amongst various processing units, few or all units can come as integrated units or available as an independent unit each.

According to one embodiment of the present technique, a user 501 aspiring to exercise an online service initiates the process using a client machine 503. The client machine 503 initiation is communicated through a network 505 to a server 507. On receiving a request for an online service by the server machine 507, the server machine 507 transmits the request to one of the suitable units 509 to generate a web-page. The system 500 further includes another unit 511 to generate a logical captcha object or analytical captcha object which is provided as a part of web-page. Further, the system 500 comprises another unit 513 to generate a query wherein the generated query is associated with the generated captcha object. Further, another unit 515 is provided to capture the user's input and to store information for the captcha object, the linked query, the correct information, and the user input. The unit 515 enabled to store the information about the captcha object provided to client machine interface, the associated query about the captcha object and correct response for the query of the said captcha object. The unit 515 is also enabled to capture the inputs provided by the user. The information is applied in authenticating process for the user as a human or not a human. The unit 517 is enabled to compare correct response for the query of the said captcha object and the input captured from the client machine interface. If the input received from the user machine & the stored correct response for the query of the said captcha object matches then the user of the client machine is authenticated as a human, if the input received from the user machine & the stored correct response for the query of the said captcha object doesn't match then the user of the client machine is authenticated as not a human.
